In 1990, in a small southwestern city, the only daughter of the Qin family tried to drown herself after her boyfriend betrayed her.
Qin Ning, from the 21st century, wakes up one day in the body of this 22-year-old unemployed woman with her head in the clouds over love.
Her parents, who dote on her, try to talk her through it while rushing around to find her a job.
A child passing by makes a face at her. “You’re a college graduate, yet all you do is embarrass your parents.”
A neighbor’s home is broken into. The husband is beaten, cash and valuables are stolen, and the robbers disappear without a trace.
Qin Ning goes to see what’s happening, when she suddenly hears the husband say, “Hit me on the left shoulder. Harder. Don’t let the police or that woman see through it.”
She realizes that the injured husband’s lips haven’t moved when she hears the voice.
Qin Ning rushes up to the criminal investigation team at the scene. “The husband staged the whole thing. The robbers are working with him. They were trying to steal the money in his home.”
Qin Ning is recruited into the criminal investigation unit. Everyone thinks the captain’s decision was too hasty, and that she only saw through the husband’s act in the burglary case by sheer luck.
But before long, she solves a case involving a missing girl that had gone cold for three years.
Later, a body hidden in a busy district, a locked-room murder, an entire family murdered in an apartment building for employees... One bizarre and difficult case after another is solved quickly with her help.
Everyone says she has a sharp eye and sees right through everything.
Only she knows that she can hear the sounds at the scene of every crime: the victims begging for mercy, the killers’ abuse, the noise near the crime scene at the time of the murder...
Using those sounds, she pieces together clues, verifies them one by one, and solves one strange case after another.
Later, everyone in the criminal investigation unit is baffled: If Qin Ning is so smart, why can’t she tell that Mr. Jiang is pursuing her?
Theme: Punish evil and promote good.
